摘　　要：文章运用大型有限元分析软件ANSYS建立32层24m×24m的巨型框架结构模型,分别对结构加载三种不同加速度峰值的ELCENTRO波、Taft波和南京波,对未设置任何支撑和设置不同形式支撑的巨型框架结构共计三组工况进行模态分析和动力反应分析,分析支撑体系的变化对巨型框架结构整体抗震性能的影响。This paper uses the large-scale finite element analysis software ANSYS to establish a 32-story 24 m × 24 m megaframe structure model and loads three kinds of waves, i.e. ELCENTRO wave, Taft wave and Nanjing wave with different peak accelerations. The modal analysis and dynamic response analysis are carried out for the mega-frame structure without any braces and with different forms of braces, and the influence of the change of the bracing system on the overall seismic performance of the mega-frame structure is analyzed.
